The pontiff warned of a "troubling decline" in cinemas and urged greater efforts to preserve the shared experience of watching films.
He described cinema as a vital "workshop of hope" and criticised the impact of digital algorithms, advocating for "slowness, silence and difference" in storytelling.
Leo encouraged artists to confront difficult themes such as violence and poverty with honesty, stating that good cinema recognises and explores pain.
His remarks come as global box office revenues remain significantly below pre-pandemic levels, with US and Canadian multiplexes recording their worst summer performance since 1981.
